I can iterate through all instances of a class in owlready2 by using the following code which works fine:

>>> for i in Drug.instances(): print(i)


But I need to iterate through all instances of the ontology (through owl:Thing). I tried the following but it doesn't work:

>>> for i in Thing.instances(): print(i)
>>> for i in onto.Thing.instances(): print(i)
>>> for i in Thing.subclasses.instances(): print(i)
